for each of the molecules below, show the dipole you would expect. you must show the direction of the dipole - arrow head pointing toward the negative end.

Question

1) CF4

2) CH3Cl

Answer 1

Look at the electronegativities(EN). That will tell you how to draw the arrow.
The EN of C is about 2.5 and that of H is about 2.1 so H is the + end and C is the arrow head.
